epp highligh for vim

I could not find a epp (puppet template language) vim highlight on the internet so I made this one. Mostly code scavenged and adapted from https://github.com/vim-ruby/vim-ruby/blob/master/syntax/eruby.vim

To make things simple, nested epp are not supported, and the syntax highlight of the underlying language is not supported either.

Contributions are welcome.

Installing with Vundle

Simply add the following to your .vimrc file:

Plugin 'rudexi/vim-epp'

Once the entry is present, perform the install via :VundleUpdate!

Installing with VIM 8 package system

mkdir -p ~/.vim/pack/plugins/start
git clone https://github.com/rudexi/vim-epp ~/.vim/pack/plugins/start/vim-epp

Using subsyntax

If you want to have syntax coloration for the language under the epp, you need to define put epp_subtype=<mytype> in a comment withing the first 5 lines of your template.

Example:

# epp_subtype=yaml
---
mykey: "<%= $my_module::mykey %>"

If you're using epp variables, you might want to put inside a comment within the epp escape:

<%-| # epp_subtype=yaml
    String $mykey,
|-%>
---
mykey: "<%= $mykey %>"
